8 3/4 inner axle seal measure or not?

[Macdon221]

Good day,

replacing inner axle seals. I did take the measurements before removing. There was about 8mm difference between the sides.

Is the difference normal?

There were no previous leaks. And no obvious groves in the axle.

Should I install the new seals close to the old measurements or should I push them in as far as they will go till they hit the lip?

thanks

Isn't there a ridge in tube to keep them from being driven in to far.

 

[Macdon221]

Yes. There is a ridge/lip.

but I read in a few posts that some people are measuring to put back in same spot. Just seemed odd to me as seals normally go pushed into the stop.

They might get stiff and not want to go in any further. Good thing you measured them first. Try it and see.

Drive them in to the step... If you don't drive them in fully it's possible that the bearing retainer ring will make contact with the seal...

One tip, pack the groove on the back side of the seal with grease.... If you don't it's likely the garter spring that applies inward tension on the seal will pop out while your installing the seal..

Great tip. Thanks

Thats a great tip. I just replaced my driver's side inner wheel seal for the second time. I get about 100 miles and then I have a leak. Hopefully what you said is my problem. here goes the third seal replacement!

Yes I’m also at that stage anymore advise, ill take it. Thanks jesse

Go with green bearing's and for get it. Put them on the runner and no issues.

I also put ultra grey around the outer edge of the seal AFTER it is installed to keep gear oil from getting around the OD of the seal

Oh ****, here we go again....

I just did this job with timken tapered bearings from Dr diff. I totally jacked up one inner seal using a large socket to hammer them in so used a block of wood the size of the axle tube and a dead blow mallet. Drove in nice and easy with wood, and hitting the stop was obvious. I used a HF slide hammer to get the old ones out.

Blue, I dont wish to debate green vs taper bearings.
But if you installed a green bearing set with no axle seals it's not going to end well.
Take it back apart and install the seals.

Ran a drag only car without the factory inner seals with the GB's and it was fine. Had over 300 passes on it.....

Ok Cranky, I am never to old to learn. I have never ran the greens but allways figured since the kit comes with inner seals they were to be installed to keep the 90wt. off the bearings.
I did not know the greens are a (wet) bearing.
Thanks.

 

[blue69runner]

Mine where sealed bearing's. Yes their was a seal to put in also. SO ALL IS GOOD. Thanks for the head's up.

The Greens are not a wet bearing but a 'sealed' bearing and not shielded. Big difference between shielded and sealed but the GB's might not be the best choice for a street driven car that see's the road regularly. Also the early ones didn't have an o-ring on the OD and those would let the rear end oil pass them by so using a sealer on the OD of the bearing was recommended. Never ran them on a daily driver but have heard about others that did and with good results with the ones that had the o-ring. I think they may have got a bad rap years ago when bearings that sat on a shelf for years before going into service and the grease in them dries up and turns to basically a soap. When that happens, the lubrication is pretty much gone. Ford and I think many GM products ran ball bearings on their rear ends and that's all a Green bearing is.....a ball bearing. Timkens take a much higher side loading but if you ain't into corner burning, then they should last a good while and it's a plus that they soak up less HP than a tapered roller does and that's one of the reasons a lot of racers like them.....especially the straight line racers.

Thanks Cranky, I did not know the ( greens) are a sealed bearing, makes sense now, lol
I had heard the new ones were a better bearing than the old greens.
The HP gain even a small ammount is prob worth the swap for a track car.

Boy I guess Mopar was a dummy wasting money on a stronger bearing when they didn't need to. Timken sure fooled a lot of us...
